The same reference numerals designate like parts throughout the severalviews.

1 represents longitudinally arranged base frame members upon oppositesides of the machine and upon which the rear end of the press chamber 2is mounted; 3 a cross member of the bed frame; 1 an axle, and 5 carryingwheels mounted thereon and supporting the rear end of the base frame.

The bottom of the press chamber includes corner angle bars 6 andcentrally arranged angle bars 7, having their upper horizontal websspaced apart, forming a longitudinal slot 8, plates 9 and angle bars 10,which are connected with the plates and support the bars 6 and 7.

The presser head includes a plate 11, having secured to its lowercorners ear portions 12, in which are secured studs, upon which arejournaled rollers 13. At the center of the plate is secured a pair ofvertical angle members 14: spaced apart and recelving between them theforward end of a plunger bar 15, and 16 designates a pin that pivotallyconnects the bar with the angle members. Below the plunger, and near thebottom edge of the plate is rigidly secured the forward end of arearwardly projecting stem 17, having its rear end connected with theupper edge of the plate by means of a rigid brace member 18, the stemand the brace forming, with the plate, a triangle, of which the stem isthe base.

19 represents a shield having its forward end secured to the presserhead and its rear end supported by means of a bar 20, having its upperend secured to the shield and its lower end to the brace member 18.

21 represents toggle members having their lower ends pivotally connectedwith depending plates 22 secured to the rear ends of angle bars 7 andtheir upper ends with the rear end of the plunger bar 15 in a mannerforming a toggle connection between the plunger bar and the base frame.A push bar 23 extends forwardly below the press chamber, having its rearend pivotally connected with the upper ends of the toggle members 21 andto the rear end of the plunger bar 15 by means of links 24. The rear endof the push bar is turned upwardly, and to its upturned end is secured aguide block 25, that is adapted to move longitudinally along the stem17.

Journaled upon laterally projecting studs 26, secured to the guideblock, are wheels 27 that roll upon the upper side of the bottom of thepress chamber, and other wheels 28 are journaled upon the bar in amanner to roll upon the under side of said bottom. The push bar projectsforward under the baling chamber, and 2-9 represents wheels journaledupon horizontal bearings upon opposite sides thereof at its forward end,that roll upon a supplemental track comprising angle sills 30 secured tobars 7, and 31 rep resents other wheels journaled upon vertical bearingsthat roll upon bars 7 and are adapted to resist a side pressure of thepush bar at its forward end.

32 represents a rack bar having its forward end pivotally connected withthe push bar and its rear end engaging with power pinions 33 secured tothe inner ends of axially alined shafts 34 journaled in verticalstandards 35 arranged upon opposite sides of the rack bar and havingtheir lower ends secured to the base frame members. The rear end of therack bar is caused to move in an orbital path relative to the pinions,and 36 and 37 represent rollers below and above the rack bar,respectively, and operative to limit the extent of its movement in avertical plane, the rollers being journaled upon short shafts connectedwith the oppositely disposed standards.

Secured to the outer ends of shafts 34 are gear wheels 38 that aredriven by means of pinions 39 upon a cross shaft 40, journaled near theupper ends of the standards. Motion is transmitted to shaft 40 through asecond cross shaft 41 journaled in bearings 42 secured to the rear endsof gear frame members 43 that are secured to the upper ends of thestandards and are inclined forward and downward and secured at theirlower ends to the base frame.

44 represents a cross bar connecting the upper ends of the standardswith each other. Secured to one end of cross shaft 41 is a pinion 45that meshes with a gear wheel 46 loosely mounted upon shaft 40 andhaving a common form of differential gear connection with the shaft andone of the pinions 39. Upon the opposite end of the shaft there issecured a friction clutch mechanism including a split ring 47 adapted toengage with internal ring portion 48 forming a part of a combined flywheel and pulley 49, loosely journaled to the shaft and held in place bymeans of a collar 50, the clutch being controlled by means of a slidingsleeve 47 connected with a common form of toggle mechanism 47 operativeto expand or contract the split ring at the will of the operator .bymeans of a longitudinally arranged rock shaft 48 having a fork 48secured to its rear end that engageswith sleeve 47 and a hand lever 49at its opposite end, and 49 represents a supplemental hand leverpivotally connected at its lower end with the press frame, the twolevers being connected by means of a link 50 in a manner permitting theclutch shifting mechanism to be operated from either side of themachine.

Upon opposite sides of the press chamber, secured to the upperlongitudinal frame members, are angle bars 51 that extend in rear of thechamber, having secured to their rear ends bearing boxes 52, in which isjournaled a rock shaft 53, and 54 represents a tie rod connectionbetween the ends of the bars.

55 represents stay rods connecting the rear ends of bars 51 with thegear frame, and 56 represents turn buckles operative to adjust thelength thereof.

Keyed to opposite ends of the rock shaft 53, adjacent the bearing boxes,are curved arms 57 that project downward and are provided with cam slots58 adapted to receive rollers 59 mounted upon studs 60 secured to thetoggle members 21 upon opposite sides of the machine.

61 represents an arm having a long sleeve portion 62 secured to the rockshaft intermediate the curved arms 57.

63 represents curved feeder arms loosely mounted at their rear ends uponthe rock jshaft at opposite ends of the sleeve 62 and connected by meansof a cross tie member 64, to which the arms are secured by means ofbolts 65. The cross tie member is held yieldingly in contact with theforward end of arm 61 by means of a compression spring 66 surrounding abolt 67 passing through the two members and having an adjusting nut 68threaded thereon. The feeder arms are curved in a manner to operateabove the press chamber and to receive at their forward ends afeederhead 69 adapted to be projected into the feed chamber in advance of theforward movement of the presser head.

70 represents a division block controllin mechanism, includingvertically arranged arms 71 pivotally connected at their lower ends withbase frame members 6 of the press chamber upon opposite sides of themachine, the arms extending upward above the chamber at a distance to beconvenient for the operator to swing them about their pivots.

72 represents vertically arranged bracket members having horizontallyarranged legs 73 secured to the arms, and 74 represents transverseseparate plates having their opposite ends secured to the arms andbracket and spaced apart in a manner to form a cage open at its ends forthe reception of a division block from either side of the machine, andopen at the bottom to allow the block to fall when the cage is movedforward above the feed chamber. When the cage is moved forward over thefeed chamber the division block will drop down upon the shield 19 and besupported thereby until the presser head is drawn rearward beyond thecage and the block is free to enter the chamber and is held in verticalposition between the presser head and spring pressed dogs mounted uponthe side walls of the feed chamber, and when the presser head is causedto advance in said chamber it causes the block to move forward with it,and the second pair of dogs 76 prevents it from returning with the head.In order to prevent a forward movement of the division block cage whenthe presser head is not in position to receive the block, there isprovided a cage-locking means including a transverse rock shaft 77journaled upon the press chamber in rear of the cage and having an arm78 secured thereto that extends rearward and is adapted to contact withav roller 79 journaled upon a stud 80 secured to one of the feeder armsin a manner to prevent any rocking movement of the shaft until thepresser head is advanced and the feeder head raised above the feedchamber. The rock shaft is provided with crank arms 81 at opposite endsthereof that are connected with the cage by means of links 82.

A condenser is provided to cooperate with the self-feeder, includingfixed side walls 83 upon opposite sides of the machine that are parallelwith the sides of the feed opening for a part of their length and thendiverge outward and rearward.

84: represents a movable condenser head secured to the bars 85 thatslide in ways provided for them in the receiving platform 86, thesecuring means including knee brackets 87 and brace members 88. Hingedto the condenser head, on vertical pivots at opposite ends thereof, areswinging members 89 that extend rearward and are formed at their rearends in a manner to slide closely against the inner surface of the fixedwalls. The swinging members are yieldingly held in contact with thefixed members by means of a tension spring 90, having its opposite endsconnected with brackets 91 that have their rear ends secured to theswinging members. The sliding bars 85 have a part thereof, toward theirrear ends, dropped to a lower plane than that of the receiving table,and are secured at their rear ends to the shield 19.

In operation the presser head is given a reciprocatory movement throughits connection with the rack and power transmitting gears, and themovable member of the condenser being connected with the presser headshield, it is thereby caused to move simultaneously therewith in amanner to present the material in a position to be engaged by the feederhead; the movement of the latter being controlled by the presser headtoggle operating mechanism, it enters the feed chamber in advance of thepresser head and is withdrawn as the latter advances.
